BUILDING CONSTRUCTION.

Application 1aed August 31, 1911;.

To aN lwhom t may concern Be it known that 1. Grzonon Mnmsn MansnALL, of the city of Winnipeg, in the lrovince of Manitoba. Canadanhave invented certain new and useful Improvements in Building Construction, of which the. following is the specitlcation.

The invention relates to improvements in building eonstrliction and the object of the invention is to provide an improved form of building block for double wall construction and also to provide a means for binding the walls formed from the blocks one to the other and to an adjoining structure.

lVith the above objectsin view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims.

Figure l represents a face view of one of the blocks. Fig. 2 represents a plan view of the same. Fig. 3 represents a plan view of a modified form of block. Fig. 4 represents a side view of the tie bar. Fig. 5 represents a vertical sectional view through a portion of a double wall constructed in accordance with my invention and showing one method ot' fastening it to an adjoining structure. Fig. (3 represents an enlarged detailed vertical sectional view showing the form of fastening appearing in Fig. 5. Fig. 7 represents a vertical sectional view through a double wall constructed in accordance with my invention showing a modified method of fastening the wall to a structure. Fig. 8 represents an enlarged detailed vertical sectional view showingr the form of fastening appearing in the modilication in Fig. 7. v

l represents a block which is formed from a suitable self-setting composition and is in the nature of a more or less thin rectangular slab. One end of the slab is fitted with an extending V-shaped tongue while the other end is supplied with a complementary V-shaped groove The upper edge of the `slab is constructed to present an extending V-shaped tongue 4` while the lower edge thereof is formed with a complementar-511V- shaped groove 5.

I wish it to be noticed that the tongues are set back somewhat from the edges of the slab to provide a bearing surface More or less centrally of the length of the block and at the upper edge thereof I have Specification of Letters Patent.

formed a cross channel 7 which follows at an even depth the contour of the upper edge of the block.

In using the blocks to build a double wall, they are set one on the other in two rows7 providing an air space between them as indi lated bv the reference letter A and when so set un the tongues at the one end andtop of a particular block receive the grooves ot' tlv, adjoining end and top block, while the grooves at the other end and bottom of the said block receive the tongues of the adjoining end and bottom hlocl. Cement or other binding material is inserted between the blocks in the respective walls to ell'ect a bond.

As the walls are being built they are connected at intervals one. to the other bv tie bars S. having lip-turned ends S and 82 designed to be received within the cross channel 7 formed in the upper dges of the blocks. As the blocks are laid on the walls these tie bars are insertedv in position and become. embedded in the cement forming the bond between the blocks. Upon the cement hardeningr the two walls are tied eli fet-tively b v the bars.

ln order that the completed double wall ma)v be connected to an adjoining structure i) such as 's'antlings or uprights, l supply hangers 1() which are fastened permanently to the uprights by screws 1l and are fitted with outstanding lower ends 10 arranged to be received within the adjoining ends of the cross channels 7 appearing between the. blocks ol the inner wall. It will be understood that the ends 10 of the hangers are cemented in the channel when the wall is being built in the same manner as are the tie bars. Upon the cement hardening the double wall is ellectively fastened to the structure.

lt will be seen that in actual practice it is unnecessary to have the cross channel in the blocks used tor thc outer wall pass cornpletely across the upper edges of the blocks. Such a block` that is. one provided with a short cross channel, is shown in Fig. 3 of the drawing.

Although l have described the double wall as constructed from blocks all provided with channels. still it will be understood that the tie bars are not necessaril)7 inserted wherever the channels appear as it is not necessary to effect a proper fastening and insure a proper strength. The builder can insert the tie bars and also the hangers Wherever he considers it advisable. v

In Figs. 7 and 8 of the drawing I have shown a modified method of fastening the wall to the adjoining structure. In this case the hangers 10 are entirely dispensed With and instead, the blocks are secured to the struct-ure by nails 12, the nails being driven into the structure in an inclined position. In actual practice the nail is driven over the under block before the top block is placed thereon and before the cement or bonding material is applied. The result is that as soon as the bonding material sets the nail is solidifyV embedded in the bond and accord'- ingly anchors the Wall to the struct-nre. In order that the nail can beu driven in in the location shownit is necessary to notch the face of the block at the end of the channel' as shown at 13.

What l claim as my invention isz- 1. The combi-nation with an inner and outer wall separated by an air space and formed from suitably bonded, substantially rectangular building blocks bearing one on the other and orovided on their ennfavin l a o n edges with complementary tongues and block and the tongue, of tie bars connecting the Walls and having their ends turned upwardly at an angle to the body thereof and received within the cross channels and embedded within the bond between the blocks.

2. The combination with an inner Wall formed from suitably1 bonded, substantially rectangular building blocks having their meeting edges provided with complementa ry tongues and grooves and a centrally located cross channel of even depth crossing the tongue bearing edges of the blocks `and an adjoining structure, of inclined nails located in the channels and embedded in the bond between the blocks and extending into the adjoining structure and effecting a fastening between the wall and the adjoining structure.
